F. OBRIEN SPRING STRUCTURE Filed Sept. 19, 1929 INVENTOR 0/76/ 0'flzv'ezy A TTORNE Y6 Patented July 21, 1931 TA T E PATET QFFEQEFALCCFNER OBH-IEN, OF DETROIT, MICHIGAN, ASSIGNOR TO L. A. YOUNG SPRING-& WIRE CORPORATION, OF DETROIT, MICHIGAN SPRING STRUCTURE Applicationfiled September 19,1929.

The main objects of this invention are:

First, to provide in a spring structure an improved brace which iseffective in supporting or bracing the parts against lateral or swayingmovement and at the same time does not interfere with or detract fromthe action of the body springs.

Second, to provide a structure having these advantages which issubstantially noiseless.

Third, to provide a structure having these advantages in which the partsare simple and economical and easily assembled.

Objects pertaining to details and economies of my invention willdefinitely appear from the description to follow. The invention isdefined in the claims.

A structure which embodies the features of my invention is clearlyillustrated in the accompanying drawings, in which:

Fig. 1 is a fragmentary plan view of a spring cushion structureembodying thefeatures of my invention.

Fig. 2 is an enlarged fragmentary vertical section on line 22 of Fig. 1.

Fig. 3 is an enlarged fragmentary perspective view showing details ofthe bracing means.

In the embodiment illustrated the body springs 1 are of the hour-glasstype, the outer springs being connected to the border frame 2 by meansof clips 3. The bottom rim 4 illustrated is of the S type, the innerchannel being clamped upon the bottom coils of the outer springs whilethe outer channel is adapted to receive the upholstery.

Certain of the springs are connected by the tie or cross members 5 ofchannel cross section, these members being secured to the 4.0 springs byclamping upon intermediate coils of adjacent springs. These members 5constitute supports for the braces.

The braces are formed of angled members 6 and 7, that is, these membersare preferably bent at 8 and 9, respectively, as illustrated. The outerend of the member 6 is provided with a laterally turned attachingportion 10 engaged by the clip 11 thereby securing the member 6 to theborder frame.

00 The member 7 is provided with a laterally with the top coils ofadjacent springs.

turned portion 12 at its outer end which is clamped within the channelof the tie member 5.

The brace members are provided with laterally disposed outwardlyprojecting pintle-like coupling engaging portions 13 at their inner endswhich are engaged within the helically coiled coupling member 14 whch ispreferably a piece of helically coiled spring.

In assembling the coupling is slipped over one of the members 13, theother member being brought into axial alinement therewith and thecoupling rotated to engage the part 13 of the brace member. The bracemembers are by this means connected so that free pivotal movement ispermitted allowing free vertical movement of the part braced withoutmaterial stress or distortion upon the brace.

I also preferably provide a cross brace for the top border frameconsisting of the brace members 15 which are connected to opposite sidesof the border frame by means of clips 16. The members 15 have couplingengaging portions lint their inner ends, corresponding to the portions13 of the brace described, and these are connected by means of a coiledcoupling member 18. The end coils of the coupling member 18 are engagedThe top frame is thus effectively braced against lateral movement and atthe same time its vertical movement is not materially restricted by thebraces.

I have illustrated and described myimprovements in an embodiment whichis found to be very satisfactory. I have not attempted to illustrate ordescribe certain embodiments contemplated as it is believed .7:

this disclosure will enable those skilled in the art to embody or adaptmy improvements as may be desired.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. In a spring structure, the combination of a'plurality of coiled bodysprings, a border frame, a tie member of channel cross section securedto a plurality of the body springs by clamping the flanges of the tiemember on intermediate 0011s thereof, a coacting pair of angled bracemembers disposed With their angles facing oppositely, and a coiledspring coupling member for the inner ends of said brace members, saidbrace members having laterally disposed oppositely projecting couplingengaging portions engaged Within the coils w of said coupling member,said brace members having laterally turned portions at their outer ends,one being clamped within the tie member and the other secured to theborder frame by means of a clip.

15 2. In a spring structure, the combination of a plurality of coiledbody springs, a border frame, a tie member of channel cross sectionsecured to a plurality of the body springs by clamping the flanges ofthe tie 3% member on intermediate coils thereof, a coacting pair ofbrace members disposed at an angle to each other, and a coiled springcoupling member for the inner ends of said brace members, said bracemembers having laterally disposed coupling engaging portions engagedWithin the coils said coupling member, said brace members havinglaterally turned portions at their outer ends, one being clamped Withinthe said tie mem er and the other secured to the border frame by meansof a clip.

3. In a spring structure, the combination of a plurality of bodysprings, a top border frame, support member secured to intermediatecoils of a plurality of body springs, a coacting pair of brace membersdisposed at an angle to each other, the outer end of the other beingsecured to said support member, and a coiled coupling member for theinner ends of said brace members, said brace members having laterallydisposed oppositely projecting coupling engaging portions engaged Withinthe coils of said coupling member.

4:. In a spring structure, the combination of a plurality of bodysprings, a top bor der frame, a support member secured to intermediatecoils of a plurality of body springs, a coacting pair of brace members,the outer end of one of the brace members being secured to the topborder frame, the outer end of the other being secured to said supportmember, and a coiled coupling member for the inner ends of said bracemembers, said brace members having coupling engaging portions engagedwithin the coils of said coupling member.

In witness whereoi I have hereunto set my hand.
